Howdy Vorts,
Is there a relationship between solar activity and earthquakes ?
An increase in seismic activity worldwide has been predicted.
How valid ? Inquiring minds want to know.
According to Richard C Hoagland, www.enterprisemission.com , there
is an explanation based on hyperdimensional physics which connects
the two. If you can understand it, please enlighten the rest of us.
I don't know anything about a hyperdimensional physics explanation,
but I can cook up a mundane explanation, so here goes ...
A change in solar radiance results in a change in mean earth
temperature. After a while this results in a change in the volume of
the earth's crust, which results in crustal expansion or contraction,
either of which can trigger pending earthquakes. Further, a relative
change in temperature between polar and equatorial regions, which
also occurs when there is a change in solar radiance, and is feedback
enhanced by local albedo changes, water evaporation rate changes
etc., results in increased wind speeds and new average wind
directions. Earthquakes have been correlated to consistent large wind
patterns. The force of wind on a content, if it is all or mostly in
the same direction, can be astronomical in size. I think the
overall effect can be so large and fast as to even momentarily
reverse relative tectonic plate motion, which is very slow anyway.
